The pump has a constant discharge at constant rotational speed. The inlet port of the pump is on the side where the gears are coming out of mesh. The discharge port is on the side of the pump where the gears are coming in to mesh. The pump transfers fluid trapped in the spaces between adjacent gear teeth and the cylinder from the inlet to the discharge side of the pump.There are virtually unlimited variations of the pump assembly possible depending on the application. The combination of the width of the gear and the speed of the pump determine the flow rate. Generally, with narrower gears, the inlet and discharge ports are NPT connections and located on the seal adapter plate. With wider gears, the inlet and discharge ports are cast flanges and located on the cylinder. Welded flanges on the Seal Adapter Plate or Cylinder may also be used should the application require them. The shaft is typically sealed with a John Crane Type 21, mechanical seal; however, the pump assembly may use Type 8-1, Type 9 or a Type 8B1 seal.<\/aside>\n<aside class=\"col-sm-4\"><center><img decoding=\"async\" src=\"https:\/\/www.apexequipmentltd.com\/wp-content\/uploads\/2018\/02\/Northern-4900-Series-img.png\" alt=\"Northern 4900 Series\"><\/center><\/aside>\n<aside class=\"col-sm-1\"><\/aside>\n<aside class=\"col-sm-4\">\n<h3>Request More Information<\/h3>\n\n<div class=\"wpcf7 no-js\" id=\"wpcf7-f1547-o1\" lang=\"en-US\" dir=\"ltr\" data-wpcf7-id=\"1547\">\n<div class=\"screen-reader-response\"><p role=\"status\" aria-live=\"polite\" aria-atomic=\"true\"><\/p> <ul><\/ul><\/div>\n<form action=\"\/index.php?rest_route=%2Fwp%2Fv2%2Fpages%2F7759#wpcf7-f1547-o1\" method=\"post\" class=\"wpcf7-form init\" aria-label=\"Contact form\" novalidate=\"novalidate\" data-status=\"init\">\n<fieldset class=\"hidden-fields-container\"><input type=\"hidden\" name=\"_wpcf7\" value=\"1547\" \/><input type=\"hidden\" name=\"_wpcf7_version\" value=\"6.1.5\" \/><input type=\"hidden\" name=\"_wpcf7_locale\" value=\"en_US\" \/><input type=\"hidden\" name=\"_wpcf7_unit_tag\" value=\"wpcf7-f1547-o1\" \/><input type=\"hidden\" name=\"_wpcf7_container_post\" value=\"0\" \/><input type=\"hidden\" name=\"_wpcf7_posted_data_hash\" value=\"\" \/><input type=\"hidden\" name=\"_wpcf7dtx_version\" value=\"5.0.5\" \/><input type=\"hidden\" name=\"_wpcf7_recaptcha_response\" value=\"\" \/>\n<\/fieldset>\n<div class=\"wpcf7-response-output\" aria-hidden=\"true\"><\/div>\n<div class=\"row\">\n\t<aside class=\"col-sm-3\">\n\t\t<p><label for=\"fname\">Name<span class=\"text-danger\">*<\/span><\/label>\n\t\t<\/p>\n\t<\/aside>\n\t<aside class=\"col-sm-9\">\n\t\t<p><span class=\"wpcf7-form-control-wrap\" data-name=\"fname\"><input size=\"40\" maxlength=\"400\" class=\"wpcf7-form-control wpcf7-text wpcf7-validates-as-required\" id=\"fname\" aria-required=\"true\" aria-invalid=\"false\" value=\"\" type=\"text\" name=\"fname\" \/><\/span>\n\t\t<\/p>\n\t<\/aside>\n<\/div>\n<div class=\"row\">\n\t<aside class=\"col-sm-3\">\n\t\t<p><label for=\"email\">Email <span class=\"text-danger\">*<\/span><\/label>\n\t\t<\/p>\n\t<\/aside>\n\t<aside class=\"col-sm-9\">\n\t\t<p><span class=\"wpcf7-form-control-wrap\" data-name=\"email\"><input size=\"40\" maxlength=\"400\" class=\"wpcf7-form-control wpcf7-email wpcf7-validates-as-required wpcf7-text wpcf7-validates-as-email\" id=\"email\" aria-required=\"true\" aria-invalid=\"false\" value=\"\" type=\"email\" name=\"email\" \/><\/span>\n\t\t<\/p>\n\t<\/aside>\n<\/div>\n<div class=\"row\">\n\t<aside class=\"col-sm-3\">\n\t\t<p><label for=\"email\">Product Name<\/label>\n\t\t<\/p>\n\t<\/aside>\n\t<aside class=\"col-sm-9\">\n\t\t<p><span class=\"wpcf7-form-control-wrap productname\" data-name=\"productname\"><input type=\"text\" name=\"productname\" class=\"wpcf7-form-control wpcf7-text wpcf7dtx wpcf7dtx-text\" aria-invalid=\"false\"><\/span>\n\t\t<\/p>\n\t<\/aside>\n<\/div>\n<div class=\"row\">\n\t<aside class=\"col-sm-3\">\n\t\t<p><label for=\"msg\">Message <span class=\"text-danger\">*<\/span><\/label>\n\t\t<\/p>\n\t<\/aside>\n\t<aside class=\"col-sm-9\">\n\t\t<p><span class=\"wpcf7-form-control-wrap\" data-name=\"msg\"><textarea cols=\"40\" rows=\"3\" maxlength=\"2000\" class=\"wpcf7-form-control wpcf7-textarea wpcf7-validates-as-required\" id=\"msg\" aria-required=\"true\" aria-invalid=\"false\" name=\"msg\"><\/textarea><\/span>\n\t\t<\/p>\n\t<\/aside>\n<\/div>\n<div class=\"row\">\n\t<aside class=\"col-sm-3\">\n\t\t<p><label for=\"captcha\">Security Code<span class=\"text-danger\">*<\/span><\/label>\n\t\t<\/p>\n\t<\/aside>\n\t<aside class=\"col-sm-2\">\n\t\t<p><input type=\"hidden\" name=\"_wpcf7_captcha_challenge_captcha\" value=\"3328806217\" \/><img loading=\"lazy\" decoding=\"async\" class=\"wpcf7-form-control wpcf7-captchac wpcf7-captcha-captcha\" width=\"84\" height=\"28\" alt=\"captcha\" src=\"https:\/\/www.apexequipmentltd.com\/wp-content\/uploads\/wpcf7_captcha\/3328806217.png\" \/>\n\t\t<\/p>\n\t<\/aside>\n\t<div class=\"row\">\n\t\t<aside class=\"col-sm-3 col-xs-6\">\n\t\t\t<p><div class=\"cf7-cf-turnstile\" style=\"margin-top: 0px;
